When asked if he’d ever pulled a Weasley twins-level prank, Radcliffe instead shared a classic story where he was the victim:

God… I should probably about the one that was pulled on ME, rather than any I pulled. Because it came from a very unexpected place.

There’s – in the 3rd film – there’s a shot in the great hall of all the kids sleeping in the great hall, and the camera starts very very wide, and comes in so that it’s an inch from my face, a very long developing set, yeah, and Alan Rickman decided he would plant one of those fart machines in my, uh, sleeping bag, and they waited until like -the camera had come in for this huge DRAMATIC developing shot, and then unleashed this tremendous noise in the great hall.

I immediately thought: “This is one of the other kids fucking around, and we were going to get in trouble.”

But as it turns out, it was one of the members of Britain’s acting royalty.

I think I laughed a lot, was probably a bit embarrassed, but it was really really funny.

Then a Redditor unearthed the actual video, and we couldn’t stop giggling:

Clearly that fart joke broke the ice, because Harry and Snape went on to be good friends:

The first few years I was genuinely quite intimidated by Alan, just because of the voice and the way he sort of carries himself. But as I grew up, I realized he was one of the kindest and most supportive members of that cast to me. I mean, Alan has cut short holidays that he’s been having to come and see me in plays, and take me out for dinner afterwards to talk to me about stuff, I think when he realized how serious I was about wanting to be an actor, and he knew what a particular world the Potter set was to grow up in, he just sort of made it his – he just really wanted to help us all and has been very helpful to me, certainly.
